Getting raw psycopg2 cursor object from a SQLAlchemy session object

I am creating a session object using this

from sqlalchemy import create_engine
from sqlalchemy.orm import sessionmaker

maiden_engine = create_engine(connection_url)
session = sessionmaker(maiden_engine)
connector = session()

Now for a certain use case, I want to get pyscopg2 cursor object from this connector object, is there a way this conversion can be achieved?

This is how you normally create a cursor object

import psycopg2
conn = psycopg2.connect(host, port, database, user, password, sslmode)
cursor = conn.cursor()

Note that this conversaion HAS to be made from connector object in the last line of first code snippet, I can not use maiden_engine or anything else.
